Application filed January 7, 1911. Serial No. 601,452.

To all whom it may concern:

Be it known that I, Josnrrr RAIcH, a subject of the Czar of Russia, anda resident of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Printing-Presses; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

This invention relates to certain novel improvements in the constructionof printing presses and consists of the matters hereinafter describedand more particularly pointed out in the appended claims.

My improved printing press embraces in its preferred form, a bed uponwhich there are mounted a plurality of traveling plates upon which arecarried the printing forms and which are adapted to pass in successionin rolling engagement with one or more impression rolls, about each ofwhich is fed a continuous strip of paper, traveling at the speed of theform bearing plates and at the peripheral speed of the impression roll,which strip receives in succession printed impressions from thesuccessively advancing plates.

In the drawings :Figure 1 is a plan view of my improved printing press.Fig. 2 isa view in side elevation of a part thereof. Fig. 3 is avertical cross-sectional view taken through the various rollers, on theline 3-3 of Fig. 1. Fig. 4 is a cross-sectional view taken upon line 44of Fig. 3. Fig. '5 is a fragmentary cross-sectional view of a part ofthe mechanism, taken on the line 55 of Fig. 2. Fig; 6 is a detail of thedriving pinions for the impression rolls, being a section on the line 66of Fig. 1. Fig. 7 is a bottom plan view of one of the form bearingplates.

In said drawings, 5 indicates the main bed of the press and 6, 6, thetraveling form-bearing plates which are preferably connected'together toform an endless train and which are moved around the main bed tosuccessively engage inking and impression rolls as hereinafter moreparticularly described.

As shown in the drawings there are eight plates 6, each of which isprovided with lugs 6 6 at its inner corners (see Flgs. 1 and 3), whichare pivotally connected to similar lugs on the adjacent plates. Animpression roll, a set of inking rolls and paper feed and re-wind rollsare located on each side of the bed 5, but as these various members arethe same in both cases, but one will be described, the other'beingindicated in the drawings by like letters of reference.

Upon the bottom of each of the plates 6 is located a rack bar 7 whichextends longitudinally of the plate along its longitudinal median line.The rack bars of said plates are successively engaged by longitu dinallyspaced cog wheels 8 and 9, which rotate in a plane parallel to thelength of the bed 5 and thus produce a continuous advancing movement ofthe train of plates 6. Said cogs 8 and 9, which project upwardly througha slot 12 in the bed 5, are mounted respectively on transverse shafts 10and 11 supported below the bed and are driven in the same direction bymeans of a pinion 13 keyed to the main driving shaft 14 which extendstransversely of the bed and is driven in any suitable manner as by thepulley 14 As said plates are engaged .by the cogs 8 and 9 they arepassed under an impression roller 15 carried upon a shaft 16 mounted insuitable standards l7, 17 upon the main bed of the press. Laterallyspaced upright guide plates 5,5 (see Fig. 4) are located below theimpression roll to hold the plates in proper alinement as they arepassed under the impression roll. Upon one end of the impression rollshaft 16 is mounted a gear wheel 18 which meshes with a gear wheel 19carried upon the shaft 10, and by means of which said impression roll isdriven.

Located above and respectively in front and in the rear of theimpression roll 15 are paper rolls 20 and 21, the shafts 22 and 23 ofwhich are slidably and rotatively mounted at their ends in slots 24formed by frame members 24 and 25 which extend diagonally upward.

In the operation of the machine the paper is unwound from theroll 20,passes under the impression roll 15 and is rewound on the other paperroll 21. A transverse feed roll 26 is rotatably supported in the framemember 25 beneath the rewind roll 21, and is provided at one end with apulley 26 driven by a belt 26 from a pulley 14 on the main shaft 14. Thepaper roll 21 rests on the feed roll 26 and is frictionally engagedthereby so as to be rotated by the rotation of said feed roll 25 to windthe strip of paper about it. As said paper roll increases the winding ofthe strip of in diameter in paper thereon, said roll rises by reason ofthe engagement of the ends of its shaft 1n the associated diagonal slotsan. A

' that plate 6 passes under the impression roll 15, ink is applied tothe printing form thereon by means of a plurality of inking rollsarranged and operating as follows: Formed integrally with the framemembers 25 upon the approach side of the impression roll are uprightbracket plates 30, 30 located at each side of the path of travel of theplates 6 and between which is supported an ink reservoir 81. Saidreservoir opens at its forward end adjacent the surface of a transverseinking roll 32 which is rotatively supported by the bracket plates 30.Upon the end of said inking roll 32 is a ratchet wheel 33 (see Fig. 2),which is engaged by a gravity controlled pawl 34: carried by a rock arm35 which is pivoted at one end upon the shaft of the inking roll 32 andat its other end to a downwardly extending link 36.

p The link 36 is pivotally connected to an opcrating arm 86 to whichmovement is imparted by a crank pin 37 on the gear wheel 19 which drivesthe impression roll. Located beneath and adapted to contact with theinking roll 32 is a second transverse roll 88 which has verticalswinging movement. Said roll 38 is mounted in the ends of two verticallyswinging rock arms 39, 39 which are secured at their ends to a rockshaft 40. Said shaft 40 is oscillated by a rock arm ll which has pivotalconnection at its end with the operating arm 36 Located beneath andadapted to be engaged by the vertically swinging roll 38 when at itslower limit of movement is a rider 42 which bears upon two form engagingrolls" 4:3 and 44: which are adapted to apply ink to the several formsas they pass beneath them. The passing of the printing form beneath andin contact with the rolls a3 and 4st rotates said rollers which in turnrotate the rider 42.

As shown in Fig. 5, the shaft 42 of the rider 42 is supported at one endin a bearing block 50 provided on its inner bearing surface with a camgroove 5O which engages a pin 42 on the shaft so that an endwisemovement of the rider 42 is produced to more evenly distribute the ink.The

plates 6, 6 are each provided wit-h casters 60, 60 which ride upon thebed 5 when the said plates are not engaged by the driving cogs. 61, 61designate chains of antifriction rollers which engage between the lowerfaces of said plates 6 and the top of the bed 5 as said plates passbeneath the impression roll. \Vhen two impression rollers are used, asillustrated, the one is operatively connected with the other throughdriving pinions 62, 62 located beneath the central portion of the mainbed 5 of the press.

The operation of the improved printing press is apparent from the abovedescription. The impression roll 15 is continuously rotated at aperipheral speed equal to the speed of travel of the form bearing plates6 and the strip of paper is continuously fed about the impression rollfrom the supply roll 20 to the rewind roll 21. The printed matter on thesuccessive forms is successively printed on the strip of paper and whenthe entire strip has passed from the supply roll to the rewind roll,said rolls may be replaced by withdrawing them through the slots inwhich they are mounted. As each form bearing plate 6 passes under therolls 43 and 4A a fresh supply of ink is conveyed thereto by the rider42 which periodically receives a supply of ink from the roll 33 by meansof the swinging roll 38. The supply of ink on said rolls is thuscontinuously renewed so that the printing form carried by each plate isinked by freshly supplied ink rolls.

w hile I have shown herein certain details of mechanical construction inillustrating one embodiment of my invention, it is to be understood thatthese may be variously modified without departing from the spirit of myinvention and I do not wish to be limited thereby except as pointed outin the respectively in the front and in the rear of said impressionroll, adapted to feed a strip of paper to said impression roll, andmeans for driving said form-bearing plates, said impression roll andsaid rewind roll at the same rate of speed.

2. In combination with a plurality of form-bearing plates, all arrangedin an end less train in the same horizontal plane, each plate beingprovided at its inner corners with lugs each pivotally connected to alug of an adjacent plate, a bed-plate on which said train ofform-bearing plates travels, a rotative impression roll adapted forrolling contact with the forms on said plates, a supply roll and arewind roll located respectively in the front and the rearof saidimpression roll adapted to feed a strip of paper about said impressionroll, horizontally spaced upright guide-plates adapted for engagementwith the lateral edges of said formbearing plates to guide them in theirtravel below the impression roll, and means for driving saidform-bearing plates, said impression roll and said rewind roll at thesame rate of speed.

3. In combination with a plurality of form-bearing plates connectedtogether to form an endless train traveling in a horizontal plane, abed-plate on which said endless train of form-bearing plates travels, arotative impression roll supported above said bedplate, a rack securedto the bottom of each of said plates, cog-wheels supported by saidbed-plate adjacent to said impression roll adapted to engage the racksof said plates in succession, a supply and a rewind roll locatedrespectively in the front and the rear of said impression roll adaptedto feed a strip of paper about said impression roll, horizontally spacedupright guide plates adapted for engagement with the lateral edges ofsaid form-bearing plates to guide them in their travel below theimpression roll, and means actuating said cogwheels, said impressionroll and said rewind roll to rotate them in timed relation.

4. In combination with a plurality of form-bearing plates connectedtogether to form an endless train traveling in a horizontal plane, abed-plate on which said train of form-bearing plates travels, a rotativeimpression roll adapted for rolling contact with the forms on saidplates, means providing inclined guide-ways adapted to receive the endsof a supply roll and of a rewind roll located respectively in the frontand in the rear of said impression roll, a supply roll and a rewind rolllocated in said guide-ways adapted to feed a strip of paper about saidimpression roll, an idle friction roll adapted for engagement with saidsupply roll, a friction feed roll adapted for engagement with saidrewind roll, horizontally spaced upright guide plates adapted forengagement with the lateral edges of said form-bearing plates to guidethem in their travel below the impression roll, and means for drivingsaid form-bearing plates, said impression roll and said friction driveroll in timedrelation.
